But now, Castor apparently has decided he’s taken enough blood from his GOP
brethren.

He announced via Twitter that he will not challenge Corbett in the May 2014
primary, saying:

After a great deal of consideration, I have decided not to
run for Governor in 2014. I want to thank all those who encouraged and advised me over the last six
months. Simply put, my duties as Montgomery County Commissioner, a lawyer with
Elliott Greenleaf, and the responsibilities to my family, make a massive
undertaking such as running governor impossible for me this election cycle. I
appreciate all of you who followed me here and on Twitter. Thank you. Bruce

Castor’s attacks against are reminiscent of how he attacked Corbett and
Asher in 2003 after Castor lost the GOP nod to Corbett for attorney general.
Castor ended up running against Corbett in the 2004 primary election where he
lost by 5 percentage points.

No word if Castor will end his criticism,
however. If he keeps it up his covert war with Corbett and Asher, Corbett might
have to fight a war on two fronts: one against a member of his own party and
one against Democrats lining up to face him.
